The mine where a piece of turquoise was found—not its color, nor its matrix, which refers to the veins and patterns of the stone—is the primary factor in determining its value. Historically speaking, the finest turquoise came from the mountains of Asia. In the 20th century, however, the copper-rich American Southwest supplanted them as the primary source of rare, and valuable, specimens, including collector favorites such as Bisbee, Lander Blue, and Number 8 (Black Web). Today, buyers are looking to China, a historical source that recently ramped up production, to supply the bulk of the world’s turquoise.
